NEW YORK/LONDON (Reuters) -Global shares edged higher in choppy trading on Tuesday, while safe-haven gold soared to a record peak as markets awaited details of U.S. President Donald Trump's tariff plans.

Investors are bracing for Trump's so-called Liberation Day on Wednesday, when he has promised to unveil a massive reciprocal tariff plan.

White House spokeswoman Karoline Leavitt said reciprocal tariffs on countries that impose duties on U.S. goods would take effect immediately after Trump announces them, while a 25% tariff on auto imports will take effect on Thursday.

An announcement is scheduled on Wednesday for 4 p.m. EDT (2000 GMT), Leavitt confirmed on Tuesday.

On Wall Street, the benchmark S&P 500 and the Nasdaq ended higher after losing ground earlier in the session, with gains in consumer discretionary communication services, consumer staples and technology stocks offset by losses in healthcare and financial equities. The Dow finished a shade lower.

"In terms of the upcoming tariff announcement, we still don't know which countries they'll be imposed on and what rate. It's fair to say that the administration might not have the final plan ready as yet," Deutsche Bank strategist Jim Reid said.

The Dow Jones Industrial Average fell 0.03% to 41,989.96, the S&P 500 rose 0.38% to 5,633.07 and the Nasdaq Composite rose 0.87% to 17,449.89.

European stocks rallied, recovering from the previous day's bout of profit-taking, particularly in assets that are highly vulnerable to U.S. tariffs.

The benchmark pan-European STOXX 600 index, which rose 5.1% in the first three months of the year, ended up 1%, with technology, industrial and financial stocks leading the way.

Uncertainty is running high. Various measures of stock, bond and currency volatility have risen sharply in the past few days, reflecting the challenge for investors of trading the unknown.

Gold eased after hitting a new record high for a fourth straight session, hitting $3,148.88 per ounce. It fell 0.15% to $3,118.25 an ounce, while U.S. gold futures settled 0.1% lower at $3,146.

Mark Malek, chief investment officer at SiebertNXT, said investors are not just faced with uncertainty from tariffs but they are also worried about the possibility of a looming economic slowdown given weakness in recent data.

Data from the Institute for Supply Management showed U.S. manufacturing contracted in March after growing for two straight months. A separate report from the Labor Department showed U.S. job openings fell in February.
